How do I make a cloth cape for LEGO?
ok, i made a &quot;quick and dirty&quot; example, how to do it.
Result: 

add a plane on ground -&gt; passive, collision (gray)
add a rigid body (active) on it (green)
add a plane, which does NOT collide with other meshes when you place it
3b) at lots of subdivision surface to plane, but not too much, else your computer explodes
add cloth modifier to plane, fix it with a vertex - pin group
raise qualitiy collisions to 20
add solidify modifier to plane with thickness -&gt; apply
check object- and self collision
increase your outer thickness of your rigid body
let the other settings of cloth as they are -&gt; little changes in the properties change a lot for the simulation

here is my blend file to check it out:
